[Raspbian] Incorrect time at boot - Raspberry Pi Forums
hello,
noticed after boot , following minutes time using or python's
way, after minutes clock automatically fixes correct value (and time keeps "flowing" correctly while pi running).
there way right time right after raspberry's boot?

there no rtc (real time clock) on pi, @ startup clock set value saved @ shutdown (and periodically in case of crash). done prevent time going backwards, can confuse both filing system , users.
however, if have network connection, pi synchronise internet time server. if network connection established during boot process, time should synchronised enough don't notice problems.
if network started manually, or not available, there may delay after booting before time can set correctly. in these cases may need add (hardware) rtc, , configure system use set system time until (and rtc) can synchronised time server.
