Very customizable beautiful clock.

There are 2 versions exist (they may co-exist):
- Digital Clock 4 - discontinued, not recommended
- Digital Clock 5 - current version, replacement for Digital Clock 4

Digital Clock 4 final version is 4.7.9
Digital Clock 5 current version is 5.1.8

Nothing special is required to start using this clock. Just launch it and enjoy! When it starts, apart from the clock itself, a small tray icon appears. This tray icon can be used to call the clock configuration dialog. Also this dialog can be called using clock context menu.

  • Great clock! I've got ver.4 running on one of my computers for a long time now, just went to get it to install on another computer and I see ver.5 available along with this message: "Digital Clock 4 - discontinued, not recommended" -- Why is it not recommended? Should 4 be un-installed? Also, latest version of MS Edge on Win 11 Pro, says: "digital_clock_5-x64.msi isn't commonly downloaded. Make sure you trust digital_clock_5-x64.msi before you open it." ... and wants me to delete it. I've chosen "keep anyway" but then Windows still blocks it from installing. (Even though i see this has had > 2000 downloads this week? Any detail on why this would be? Or any tips? Note.. I do know how to unblock files but it always makes me hesitate to install when this occurs. Thank you!

    ver.4 is not recommended as it is built with old tools, and who knows how it will behave in new environment, especially with HighDPI displays. know nothing about MS Edge downloads, maybe this something about SourceForge and how it works in MS Edge, or maybe just because my installer is not signed and MS enforces signed installers even there. Firefox never complained. unsigned installer is also the reason why Windows shows warning on run/install.
  • Nick-korotysh the Digital Clock program is excellent. I use it frequently for on-screen timestamps for video recordings. A thought - many of use OBS for streaming for all kinds of purposes. A common request is to use OBS to overlay a clock into the stream using a local file with a simple script and a bit of HTML. Easy enough for someone with a bit of coding skills, but fussy as heck to skin and rocket science for someone looking to add a bit of graphic fun on the fly. Digital Clock's appeal is powerful configurability in a simple way so the results look great! Could the application serve up the same nicely configurable clock, but as HTML rather than display? I would much rather tweak and configure Digital Clock outside OBS and have the results change in real-time in my stream. Oh yeah, any chance you could put Major, Minor, Build in the release file names? Not a biggee, but I keep copies of the installers in case I need to revert and a version stamp in the file name helps keep them separate.

    thanks for the review. what about questions/suggestions, contact me by email or create issue/discussion on GitHub and provide more details. it is not so clear what you want to see.
  • Excellent desktop clock & day/date app. Only the features that are needed: no fluff, no junk. Small issue: unlit segments of 7-segment numeric display are always visible, although faded

    thanks for the review! the mentioned faded segments are part of the skin, I'll include new skin without them in the next version, as some users contacted me with the same complaints
  • Custom backgrounds are so cool ! I hope to add the alarm clock plugin as soon as possible.This is an important feature.

    I understand that alarm is quite important feature, but unfortunately this is unlikely be added because it will be completely useless and unreliable. nowadays most of the systems (especially Windows) goes to "deep sleep" mode if computer "left alone", in this case the only working time source is RTC (hardware clock), and only low-level OS stuff has access to it, whatever apps are just doesn't work. so, implementing alarm clock in regular app is just unreliable - it will not do its job if computer will be in sleep mode. the only only way I see - to use system-provided clock/alarm apps for that purpose, but also test them several times before "relying on them", as who knows what's behind them (especially taking into account various "sandbox" technologies common for "app-store apps"). and it is very unlikely that the regular app can get access to RTC, and even more somehow wake-up computer when it needs, such operations are privileged by design, only very few system-specific utilities can get access to it. preventing sleeping is not an option, and this is also will be privileged operation too. and who wants to run some small unknown 3rd-party app in privileged mode or have some hidden privileged system services running for that purpose (this is a common hack nowadays)? so, all these things lead to very complicated platform-specific implementation and still provide almost no reliability, hence it just doesn't worth (especially taking into account the fact that I'm not a Windows developer).
  • Thanks for your app, it's great. There are just not enough hotkeys to hide the time or hide in full screen mode in games and watching movies in the browser.

    thanks for the review! there is an option that controls clock behavior in full screen mode ("show in fullscreen mode"), you can can disable it, then clock will not appear in fullscreen apps (at least it should). unfortunately, it is too problematic to implement some global hotkeys, library I used for this purpose previously seems not maintained anymore and barely usable now.
